BMW Strut Braces & Stress Bars for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

BMWs need some added chassis strengthening in the front. You may notice some "chassis flex" when cornering or driving over a bumpy road. The reason for this is the incredible amount of force being applied to front strut towers. They have a tendency to flex when force is applied to them. Tying the strut towers together with a brace reduces the amount of flex and soldifies your car's chassis. Easy installation.

A strut tower brace adds additional reinforcement to the front strut towers, tying them together for extra rigidity. This makes the whole structure stronger with less chassis flex. Handling and steering feel are improved with better turn-in and input with no downsides. The Dinan strut tower brace is a very high quality aluminum brace with precision machined ends that match the contours of the strut tower. Other braces simply sit on top which reduces their effectiveness. This is definitely one of the stronger strut brace designs on the market. The center bar is polished aluminum with carbon fiber inlays - an unmistakable sign of precise engineering when you open the hood.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. This part is worth 2 points towards your Dinan badge.

The Carbon Fiber ECS strut tower bar kit offers more than just good looks - it also serves to protect strut towers from "mushrooming" or other deformation caused by rough roads or vehicles with stiff suspension and helps to triangulate the front end, providing more consistent suspension geometry with less chassis flex. Strut tower plates should sit flush against the strut towers. If this is not the case, your strut towers are to some extent deformed. This can be easily remedied in minor cases with a block of wood and a hammer. Carbon fiber is an excellent addition to any vehicle and offers a very unique look that is found on some of the most exotic vehicles on the road today. This strut bar kit features a clean woven design that is sure to look phenomenal for years to come and will compliment absolutely any engine bay. Don't settle for a boring stainless steel or aluminum strut bar, your BMW deserves the best. Features high gloss carbon fiber bar and black CNC machines tower plates with stainless steel hardware. Not for SULEV M56 engine models.
